Abstract:

A crystal-structure analysis of iodinin, 1,6-phenazine diol-5,10-dioxide C12H8N2O4, was carried out at --160C and at room temperature. The crystals are monoclinic, space group P21a, with at -- 160C a15.634, b5.028, c6.037 A, beta91.00 deg., Z2. The structure was determined entirely by symbolic-addition methods and refined by block-diagonal least-squares to a final R index of 0.060. The structure consists of endless ribbons of nearly coplanar molecules, extended in the directions 011. Adjacent molecules in a ribbon are linked by the intermolecular branches of bifurcated hydrogen bonds. The binding force is sufficient to cause a non-bonded oxygen-oxygen contact of 2.591 A. Author
